First it starts with a comedy video which turns into this weird creepy thing about kids running through the Paris sewers, encountering an alligator, then getting rowed out and into the Seine by a ghost and it cuts to reality and all the nations are going down the river on boats past a bunch of water jets because they're not doing this in a stadium.
This looks awful and ridiculous. Compare this to the spectacle of London 2012.
Now they're doing some weird old Hollywood movie musical style musical number with Lady Gaga and she's on a staircase, which is... somewhere in Paris?
I am so fucking confused.
Edit: They just cut to Macron and he looks as confused as I am.
He's carrying the torch to light the Olympic "bonfire"...I guess...but I don't know the relation to anything mystical that they may be hinting at with Assassin's creed...c'est une surprise :3
